矿用机械式风速表是用于煤矿井下测量风速的仪表 ,准确与否直接影响着煤矿的安全生产 ,故将风速表列入强制检定范围 ,规定每半年必须检定一次 ,由于风速表是机械式传动 ,再加上风速表使用时 ,处于煤矿井下特殊的生产环境 ,因此在检定中 ,风速表经常出现这样那样的故障 ,以ＤＦ Mine mechanical anemometer is used in coal mine wind speed measurement instrument, whether it directly affects the accuracy or safety of coal mines, it will be included in the compulsory verification of anemometer range, the provisions must be tested every six months, the anemometer is a mechanical Transmission, coupled with the use of anemometer, in a coal mine special production environment, so in the test, the anemometer often appear such a failure to DF
